from the first debate between president obama and republican challenger, mitt romney. some are calling these debates a make-or-break moment for romney. it's "your voice, your vote." with just 38 days left to election day. and david kerley joins us from the white house with an inside look at how both sides are prepping. david? >> reporter: good morning, bianna. this is the year that these debates could be critical. so, both candidates are spending a lot of time preparing. heading back to boston for more debate practice, mitt romney would not endorse the view that the debates could be do-or-die for his campaign. >> i don't think anyone would suggest that the debates are not important. i can't tell you how important it will be. it will be a good chance for the president and for me to have a conversation with the american people about our respective views. >> four more years. >> reporter: mr. obama spent a couple of hours practicing yesterday, as well. and has three days set aside for more practice. it's nicknamed debate camp. and near the end of camp, like now, it's a full-on mock debate.
